The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Of flat-four configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively.
The two variants shared the same bore, stroke and compression ratio. The C85 produced ten extra horsepower by virtue of having a maximum permissible rpm of 2575 versus the 2275 of the C75.
The C75 was in production from 1943 to 1952 and the C85 from 1944 to 1970.
